Abstract

This disclosure provides a document access method and system. The document access method and system are based on a social network model which interconnects members of the social network as a function of trust. This framework provides a basis for documents to be accessed by members which are not directly specified by a document'"'"'s owner, while providing a certain degree of document security.

Claims

1. A method of operating a document access system, the document access system including one or more servers and a plurality of member computers, the member computers operatively connected to the one or more servers, the method comprising:

the document access system generating a model which represents all members of an information technology social network, the model associating an intermember trust value for each member relative to each other member of the social network;

the document access system associating a document trust value requirement and document owner for one or more documents, the document trust value requirement providing a minimum intermember trust value, relative to the document owner, necessary for access to a respective document; and

providing access to a document for a set of members as a function of an effective trust value associated with the shortest path from the document owner'"'"'s vertices to each respective member, wherein the shortest path is a function of connecting intermember trust edges from the document'"'"'s owner to the respective members,

wherein generating a model comprises;

generating a directed graph G (V, E) representing the social network, where V represents the people as vertices and E represents the intermember trust as edges.

2. The method of operating a document access system according to claim 1, the effective trust value calculated according to the method comprising:

multiplying each edge trust value associated with each path from the document'"'"'s owner to the other members.

3. The method of operating a document access system according to claim 2, further comprising:

comparing the document'"'"'s trust value with the effective trust value associated with each other member, relative to the document'"'"'s owner; and

providing access to only members with an effective trust value greater than or equal to the document'"'"'s trust value.

4. The method of operating a document access system according to claim 1, the method comprising:

generating a database for storing document'"'"'s trust attributes and member trust attributes.

5. The method of operating a document access system according to claim 4, the method comprising:

interfacing with members to acquire data for the database.

6. The method of operating a document access system according to claim 1, the method comprising:

informing members which documents they can access.

7. A method of operating a document access system, the document access system including one or more servers and a plurality of member computers, the member computers operatively connected to the one or more servers, the method comprising:

the document access system generating a model which represents all members of an information technology social network, the model associating an intermember trust value for each member relative to each other member of the social network;

the document access system associating a document trust value requirement and document owner for one or more documents, the document trust value requirement providing a minimum intermember trust value, relative to the document owner, necessary for access to a respective document;

comparing the document trust value with an administratively determined minimum trust value; and

attributing the administratively determined minimum trust value to any document associated with an owner assigned document trust value greater than the minimum trust value.

8. A document access system comprising:

one or more servers; and

a plurality of member computers, the member computers operatively connected to the one or more servers, the one or more servers executing a method comprising;

the document access system generating a model which represents all members of an information technology social network, the model associating an intermember trust value for each member relative to each other member of the social network;

the document access system associating a document trust value requirement and document owner for one or more documents, the document trust value requirement providing a minimum intermember trust value, relative to the document owner, necessary for access to a respective document; and

providing access to a document for a set of members as a function of an effective trust value associated with the shortest path from the document owner'"'"'s vertices to each respective member, wherein the shortest path is a function of connecting intermember trust edges from the document'"'"'s owner to the respective members,

wherein generating a model comprises;

generating a directed graph G (V, E) representing the social network, where V represents the people as vertices and E represents the intermember trust as edges.

9. The document access system according to claim 8, the effective trust value calculated according to the method comprising:

multiplying each edge trust value associated with each path from the document'"'"'s owner to the other members.

10. The document access system according to claim 9, the method further comprising:

comparing the document'"'"'s trust value with the effective trust value associated with each other member, relative to the document'"'"'s owner; and

providing access to only members with an effective trust value greater than or equal to the document'"'"'s trust value.

11. The document access system according to claim 10, the method comprising:

generating a database for storing document'"'"'s trust attributes and member trust attributes.

12. The document access system according to claim 11, the method comprising:

interfacing with members to acquire data for the database.

13. The document access system according to claim 8, the method comprising:

informing members which documents they can access.

14. A document access system comprising:

one or more servers; and

a plurality of member computers, the member computers operatively connected to the one or more servers, the one or more servers executing a method comprising;

the document access system generating a model which represents all members of an information technology social network, the model associating an intermember trust value for each member relative to each other member of the social network;

the document access system associating a document trust value requirement and document owner for one or more documents, the document trust value requirement providing a minimum intermember trust value, relative to the document owner, necessary for access to a respective document;

comparing the document trust value with an administratively determined minimum rust value; and

attributing the administratively determined minimum trust value to any document associated with an owner assigned document trust value greater than the minimum trust value.

15. A document access system network comprising:

one or more servers; and

a plurality of member computers, the user computers operatively connected to the one or more servers,

wherein the one or more servers execute computer readable instructions to generate a model which represents all members of the document access system network, the model associating an intermember trust value for each member relative to each other member of the document access system network, and the one or more servers execute computer readable instructions to associate a document trust value requirement and document owner for one or more documents, the document trust value requirement providing a minimum intermember trust value, relative to the document owner, necessary for access to a respective document, and

wherein the one or more servers execute computer readable instructions to compare the document trust value with an administratively determined minimum trust value, and attribute the administratively determined minimum trust value to any document associated with an owner assigned document trust value greater than the minimum trust value.

16. The document access system network according to claim 15, wherein the one or more servers are configured to generate a directed graph G (V, E) representing the document access system network, where V represents the members as vertices and E represents the intermember trust as edges.
